EIGRP 非等价负载均衡

1、eigrp 非等价负载均衡eigrp 既支持等价 也支持非等价负载均衡 下面做非等价负载均衡 650) this.wth=650;" src="/uploads/allimg/111214/12551l463-0.gif" border="0" alt="" /> 首先要满足的是要有fs 假如惟独cceesor 没有fs 那么就不会产生非等价不在均衡 非等价负载均衡主要是调variae值 variance值*fs的fd successor的fd就可以了。 从上面的拓扑图很简单看出去往1.1.1.1这个网段绝对是走以太网

2、口 由于以太网的带宽大 r3show ip eigrp topology all-links ip-eigrp topology table for as(90)/id(3.3.3.3) p 1.1.1.1/32, 1 successors, fd is 409600, serno 31 via 13.1.1.1 (409600/128256), ethernet1/0 via 23.1.1.2 (2809856/2297856), serial0/1 ad successor的fd 不能成为fs p 2.2.2.2/32, 1 successors, fd is 2297856, serno

3、 29 via 23.1.1.2 (2297856/128256), serial0/1 via 13.1.1.1 (2323456/2297856), ethernet1/0 p 3.3.3.3/32, 1 successors, fd is 128256, serno 8 via connect, loopback0 p 12.1.1.0/24, 1 successors, fd is 2195456, serno 32 via 13.1.1.1 (2195456/2169856), ethernet1/0 via 23.1.1.2 (2681856/2169856), serial0/1

4、 p 13.1.1.0/24, 1 successors, fd is 281600, serno 24 via connected, ethernet1/0 p 23.1.1.0/24, 1 successors, fd is 2169856, serno 1 via connected, serial0/1 我们就要通过调节k值来让它成为fs 我们调节延迟 把以太口的延迟调节为100000 r3(config)int e1/0 r3(config-if)delay 10000 重新查看拓扑表 p 1.1.1.1/32, 1 successors, fd is 2809856, serno

5、45 via 23.1.1.2 (2809856/2297856), serial0/1 via 13.1.1.1 (2944000/128256), ethernet1/0 ad successor的fd 成为了fs 现在我们可以做非等价负载均衡了 只需将variance值调节为2即可 r3(config)router eigrp 90 r3(config-router)variance 2 查看r3的路由表 r3show ip route 1.0.0.0/32 is subnetted, 1 subnets d 1.1.1.1 90/2809856 via 23.1.1.2, 00:00:
